Effect of the underlayer on the elastic parameters of the CoFeB/MgO heterostructures
Scientific ReportsWe investigated the thermally induced surface acoustic waves in CoFeB/MgO heterostructures with different underlayer materials. Our results show a direct correlation between the density and elastic parameters of the underlayer materials and the surface ...

Tailoring MBE growth of c-Mn3Sn directly on MgO (111) from islands to film
npj Quantum MaterialsWe present our study of (0001) oriented Mn3Sn (c-Mn3Sn) thin films synthesized directly on an MgO (111) substrate via molecular beam epitaxy. We identify a growth window where Mn3Sn growth can be controlled through slight adjustments of the Mn flux ...

Bending-strain effects in conventional superconductors and superconducting junctions
npj SpintronicsWe consider the effect of bending-strain in thin films of clean, conventional superconductors (S), and the proximity-induced effect of this strain in SN bilayers with a normal metal (N), and SNS junctions with equal curvatures in each superconductor.
